Type 630R Relief Valve

Introduction

The Type 630R is a general relief valve that is

available in NPS 1 and 2 / DN 25 and 50 body sizes.

It is frequently used at compressor stations, re neries

and similar plants requiring a backpressure gas

regulator for relief pressure settings up to 250 psig /

17.2 bar.

  —The Type 630R is available in both

high-pressure and low pressure constructions; the

low pressure units have larger diaphragm area

to provide more accurate control of low pressure

settings while the high-pressure units can withstand

inlet pressure up to 550 psig / 37.9 bar and can

control pressures up to 250 psig / 17.2 bar.

can be easily converted in the  eld to a Type 630

regulator by reversing the actuator and using a new
